An apparatus and method for removing fractions of a pixel from bar code bars to maintain the correct distance between adjacent correctly sized code forming bars. Thus, the distance between adjacent code forming bars will be constant and accurate. The foregoing is accomplished by varying a parameter of the beam or ink droplet that is used to produce the bar so that the bar width and space between adjacent code forming bars will be accurately maintained. Hence, bars of a bar code will be accurately reproduced to enable the bar code to be accurately read.

Cette invention concerne un dispositif et une méthode de réduction d'un pixel formant une barre d'un code à barres pour mainyenir un espacement approprié entre barres adjacentes de dimensions correctes formant le code à barres. Cette réduction est réalisée en variant les paramètres du faisceau ou de la gouttelette d'encre utilisés pour produire la barre de manière que les spécifications d'épaisseur et d'espacement des barres et leur espacement soient rigoureusement respectées. Ainsi, les barres du code seront réalisées avec une précision rehaussant leur lisibilité.
